Allusions to the movie Die Hard:
Peter DeLuise: And because we're vulnerable, and we have to evacuate the city, the Genii come in a terrorist act, and actually attack us when we're most vulnerable and we only have a skeleton crew there. They come to take our crap, and they try to kick our butts. That's kind of a 'Die Hard' episode where Joe [Flanigan] is sneaking around the hallways and kicking the crap out of the bad guys.
Actor Robert Davi, who plays Commander Kolya also played FBI Johnson in the film Die Hard.
